Description
Compared with other compounds in its class, the molecular weight of 276.20 g/mol gives Dimethyl (3-(4-fluorophenoxy)-2-oxopropyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dimethyl (3-(4-fluorophenoxy)-2-oxopropyl)phosphonate (CAS 55444-94-5), molecular formula C11H14FO5P and molecular weight 276.20 g/mol, is a CATO reference standard with documented purity and traceability.
Dimethyl (3-(4-fluorophenoxy)-2-oxopropyl)phosphonate (C11H14FO5P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Dimethyl (3-(4-fluorophenoxy)-2-oxopropyl)phosphonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
